REPORTING FORMAT FOR THE ANALOGUE APPROACH

1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Barium hexaferrite shares common functional groups with iron oxides.

2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
No purity information is available (data from secondary source).

3. ANALOGUE APPROACH JUSTIFICATION
Both barium hexaferrite and iron oxides are water insoluble, powdered substances. In contact with eyes, in the clinical experience they behave similarly.
